What Is the Hexagon Perimeter Calculator?
This calculator finds the perimeter of a regular hexagon — a six-sided polygon where every side has the same length. The perimeter is simply the total distance around the shape. Because all six sides are equal in a regular hexagon, you only need to know the length of a single side to compute the whole perimeter.
How to Use It
Enter the length of one side (s) of your hexagon into the input field and the calculator instantly returns the perimeter. The side length can be in any unit (cm, m, inches, feet) — the perimeter will be in the same unit. Make sure all your measurements use the same unit before calculating.
The Formula Explained
The perimeter of a regular hexagon is given by:
$$P = 6 \times s$$
Here, \(P\) is the perimeter and \(s\) is the length of one side. Since a regular hexagon has six identical sides, adding them together (\(s + s + s + s + s + s\)) is the same as multiplying one side by six.
Worked Example
Suppose a regular hexagon has a side length of 5 cm. Plugging into the formula: $$P = 6 \times 5 = 30 \text{ cm}$$ So the hexagon's perimeter is 30 cm. If the side were 12.5 inches, the perimeter would be \(6 \times 12.5 = 75\) inches.
FAQ
Does this work for irregular hexagons? No. The \(P = 6s\) formula assumes all six sides are equal (a regular hexagon). For an irregular hexagon, add the six side lengths individually.
What units does the result use? The perimeter comes out in whatever unit you used for the side length. Centimeters in, centimeters out.
How is perimeter different from area? Perimeter measures the distance around the boundary, while area measures the surface enclosed inside. They use different formulas and different units (linear vs. square units).
